The term “csc x” stands for the cosecant of angle x

The term “csc x” stands for the cosecant of angle x. In trigonometry, the cosecant of an angle is defined as the reciprocal of the sine of that angle.

Mathematically, we can express the cosecant of angle x as:

csc x = 1/sin x

Where sin x represents the sine of angle x.

To find the value of csc x, we need to know the value of sin x. The sine of an angle can be determined using a trigonometric table, a calculator, or by using the unit circle. Since the cosecant is the reciprocal of the sine, if you have the value of sin x, you can simply take its reciprocal to find csc x.

For example, if sin x = 1/2, then:

csc x = 1/(1/2)
= 2

So, csc x would equal 2.

It is important to note that the cosecant function is undefined for certain values of x where the sine of x is zero. This occurs at angles where the sine function crosses the x-axis. At these angles, the cosecant becomes undefined because division by zero is not allowed in mathematics.
